Are there any out there? I know I've seen a few "clone" scripts for PTC sites, but my main question regarding these is are they legal to use? I was planning on opening a few sites like these in the future, but I do not want to use something that will legally get me in trouble.

Also, if there are no free scripts that are legally allowed to be used, when you buy a script from a company, do they normally give you the rights to re-use that scripts on however many sites you bring up?

Thanks for the information.
